When the door 39 is opened as shown in FIG. 14 from a state where the door 39 is closed as shown in FIG. 16, a center of the upper end portion 75 of the door 39 is formed. When the door 39 starts rotating against the protrusion 74 and further rotates to the maximum rotation position, the upper end portion 75 slides on the inclined surface of the protrusion 74 and the upper end portion 75 is elastically deformed.
, And the open state is maintained by the friction locking. When closing the door 39, the door 39 can be closed by rotating in the closing direction against the frictional resistance with the projection 74.

According to this embodiment, when the switch 8 is manually operated, it is not necessary to remove the cover 26 from the electric device disposition base 25, and the operation is performed by opening the operation hole 38 by operating the door 39. Insert the fingertip through the hole 38 to open the switch 8
Can be operated. For this reason, the possibility that the hand directly touches anything other than the switch 8 is reduced. Lid 3
9 has a circumferential groove 60 around the operation hole 38,
There is a drain groove 61 extending from the lower peripheral groove 60 a of the operation hole 38 to the end of the lid 26, and the door 39 is attached to the upper peripheral groove 60 b of the operation hole 38 so as to be openable and closable. The door 39 and the cover 2 have
6 can prevent water from entering the inside by the side walls 67 and the circumferential groove 60 on both sides, and can prevent water from entering the gap from passing through the drain groove 61 to the lid. It is possible to quickly drain from one end of the body 26.

A stepped concave portion 62 is formed on the inner surface of the peripheral groove 60 between the hole end 38a of the operation hole 38 and the bottom surface 60e of the peripheral groove 60.
Therefore, when the door 39 is opened, it is possible to prevent water adhering to the side wall 67 and the like of the door 39 from flowing along the end of the operation hole 38 and entering the inside of the lid 26. When the door 39 closes the drain hole 61 with the operation hole 38 closed, the handle 63 is moved to the door 3.
9, the handle 63 can be operated by inserting a fingertip into the end of the drain groove 61.
Opening and closing operation becomes easy.

When the door 39 is closed, an extension 64 extends below the operation hole 38, and a contact portion 65 with which the extension 64 abuts is formed on the lid 26. Since the extension portion 64 is in contact with the contact portion 65 of the lid 26 in a state where the cover 39 is closed, it is possible to prevent the door from being damaged due to the impact of the object. Since the door 39 and the lid 26 are provided with the holding means 74 for holding the door 39 in the open state, the door 39 is held in the open state, so that the switch 8 can be easily opened and closed.
